- Circle hook
A circle hook is a type of fish hook which is sharply curved back in a circular shape. It has become widely popular among anglers in recent years because it hooks a much higher percentage of fish and is rarely swallowed. Since the circle hook catches the fish on the lips at the corner of its mouth, it greatly decreases the mortality rates of released fish as compared to J-hook (like O'Shaughnessy or Octopus hooks) which is swallowed by the fish causing it to set in the gills or vital organs.
The circle hook's unique shape allows it to only hook onto an exposed surface, which in the case of a fish means the corner of its mouth. The fish takes the baited hook and swallows it, and as the hook is reeled in, it is safely pulled out of the fish until it reaches the mouth. At this point it will catch the corner of the mouth of the fish, resulting in fewer gut-hooked fish.
In terms of technique, it is important to not strike when the fish bites, but rather just reel in. The act of striking while using a circle hook often results in the hook being pulled out of the fish altogether.
